USE
Add sodium sulphite mother liquor (containing NaHSO3 40%, Ph value of 3 to 4) slowly into soda ash to generate sodium sulfite solution (to the slurry Ph value of 7~8 for the end); transfer the above sodium sulfite solution into series reactors (2 to 3) to absorb the SO2 gas (10% to 13%) from the combustion of sulfur, forming sodium bisulfite (to the reaction temperature no longer rising for the end). In the reaction process, a large number of crystals precipitate out, which is centrifuged to obtain the wet goods with moisture content of 6% to 10%, and then dehydrated by air drying at 250 to 300 ° C to make the final products.<br />
2NaHSO3 + Na2CO3 → 2Na2SO3 + H2O + CO2↑<br />
NaSO3+H2O→2NaHSO3<br />
Absorb sulfur dioxide from the gas of sulfuric acid production with soda ash solution to generate sodium bisulfite. After further centrifugal separation and air drying at 250~300 ° C, the final sodium bisulfite is obtained. <br />
Na2CO3 + 2SO2 + H2O → 2NaHSO3 + CO2↑
